You were not being nice. You were being scared. You seek for beauty and a nice smile in a woman, woman seek for dominance, confidence and leadership in a man. She is not going to chose the guy that is being pushed around just as much as you are not going to pick the ugly girl. You still can be nice and confident and leading, but it's way easier to just be a dick and have these attributes.

Incorrect. That's a really wrong point. Different women look for different things. Also being nice doesn't mean you're scared. Being nice is being nice. It has nothing to do with being scared.

Second, this has nothing to do with "the ugly girl". This is about personality. Or are you going to tell me a woman is going to pick the dominant confident leader if he is an ugly guy in her view? No, she's not.

Yes, it is easier to be a dick and have all those attributes... but that just means you're taking the easy wrong way. And any woman going for the dicks are also going for the easy way and it will 100% hurt them in the long run.
